Let's save the transport object and return to the configuration field "Transport address" of the controller object and select the address "Sockets.CM101". Currently OpenSCADA supports for controller objects of most data source types to specify all transport parameters directly in the field "Transport address" and without need in separated creation any transport objects. That is pointing in the field for "Sockets.CM101:localhost:10502" will automatic create CM101 in the Sockets output transports with the specified address.
